Need Some TE Advice

.5 PPR. Graham is my current TE and I have Olsen stashed on my bench. Graham is on bye next week, along with my QB and two of my three WRs. So I’ll likely be dropping Graham next week in order fill my roster (Got no one else to drop). OJ Howard is also on FA right now. If I’m not able to get Graham back after week 7, who is the better ROS TE? Olsen or Howard?
